Netapp and VMware... It's all so confusing!
by Timothy Hollingworth 01 Apr '10

01 Apr '10

So, say for example, I want to virtualize an Exchange server. Lets also say that I want to manage it via Snapdrive and SME. Lets also say, just for the heck of it, that I want both the new front-engined Acura NSX as well as the Porsche RC3. The cars aside, I would have to run iSCSI from within the VM, install and use Snapdrive from within the VM to provision LUNs, install Exchange and then use SME? It seems kind of silly to use iSCSI from within a VM if the ESX box were fiber attached to the Filer, just to be able to use Snapdrive and SME, no? I would love to be able to use the features of SD and SME within a completely virtual environment and am wondering what some real world implementations other VMware/Netapp customers are running. Do you run storage for the databases and logs in VMDK's and manage snapshots and backups from a VMware virtual machine perspective or do you manage them as iSCSI LUNs and use SD and SME? Or am I completely blind and missing something? Timothy L. Hollingworth Sr. Network Engineer, ePlus Technology Inc. 678.462.6698 (cell) AIM: HollingworthTim YIM: t_holling

how to "move" an existing snapmirror to new network interfaces?
by Todd C. Merrill 18 Aug '08

18 Aug '08

I have lots of existing q-tree snapmirrrors of the form: srcfiler:/vol/volM/qtreeX destfiler:/vol/volN/qtreeY "srcfiler" (DNS name) is the e11 interface on srcfiler "destfiler" (DNS name) is the e9a interface on destfiler We just built a "dedicated snapmirror/backup" network and added the following: "srcfiler-backup" (DNS name) is the e0 inteface on srcfiler "destfiler-backup" (DNS name) is the e11a interface on destfiler Subsequent 'snapmirror update -S ...' commands (we don't use snapmirror.conf) still use the non "-backup" network links. I'm not seeing the counters on the "-backup" links increment via the `ifstat` command. The $64,000 question: --------------------- How do I "move" these snapmirrors to the "-backup" network links...without, of course, re-initializing them? I'm expecting, in the end, to see `snapmirror status` give back to me: srcfiler-backup:/vol/volM/qtreeX destfiler-backup:/vol/volN/qtreeY and see the counters on e0 on srcfiler and e11a on destfiler increment.

RE: filer to vfiler conversions
by Villabroza, Gerald 01 Jul '08

01 Jul '08

Because each vfiler needs its own ip address there may not be a way to unassign the ip from the root vfiler (vfiler0) and assign it to a vfiler (vfiler1) with zero downtime. You can certainly use a new ip for vfiler1 and make DNS changes so the old name points to the new ip. This isn't zero downtime, but depending on your DNS mechanics it can be very low. If you're running cifs on vfiler0 and want to move those resources to vfiler1 you have no choice but to take a short outage since cifs is stateful and the mac address will be different between vfiler0 and 1. We've been running multistore for over a year now and in most cases the vfiler resources are segregated from the physical vfiler0. If others have an idea on how to do this with zero downtime I'd be happy to be wrong. -=--=- gerald villabroza <geraldv at stanford.edu> technical lead, its storage, stanford university -----Original Message----- From: scott.belisle(a)americas.bnpparibas.com <scott.belisle(a)americas.bnpparibas.com> Sent: Monday, June 30, 2008 8:23 AM To: owner-toasters(a)mathworks.com <owner-toasters(a)mathworks.com>; toasters(a)mathworks.com <toasters(a)mathworks.com> Subject: filer to vfiler conversions Hi, Quick question for any multistore users out there. I have a physical filer that I want to convert to a vfiler. However, I need to keep the same IP and DNS information intact, and don't want to incur any downtime. Is there a way to do this without having to take down the physical filer to change it's name/ip? We are running 7.2.3 on a 6030 with CIFS & NFS. Thanks!

Replacing Disk Shelves
by ifstat 30 Jun '08

30 Jun '08

Hi Toasters, A customer of mine has reached the limit on the FAS3050C, in terms of shelves and disks. So inorder to allocate additional storage space, we are replacing the 36gb disk with 300gb. However, we also need to replace the DS14, with DS14MK4 shelves becuase of better throughput between DS14 & DS14MK4. Can someone please confirm the proceedure of doing this without interuption. Logic says that: 1) Destroy any aggregates on the 36Gb disks. 2) Zero all spares 3) Remove ownership from the 36Gb disks 3) Disable the Cluster 4) Disable the FC HBA's that are link to the DS14 shelves that are being replaced. 5) Power cycle the shelves 6) Replace the shelves and repeat the above in reverse. -- View this message in context: http://www.nabble.com/Replacing-Disk-Shelves-tp18170304p18170304.html Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

SnapManager SQL Errors
by Raj Patel 27 Jun '08

27 Jun '08

Hi, We're just setting up a new SQL server with a SMSQL backup job and we're seeing the following DBCC errors. The SM SQL job has been re-installed and the job setup again as per other servers (ie its the first time we've seen the error). There is also an initiator error but we're not sure why thats listed as an issue - it through the initiator and that IP that the SAN lun's are connected in the first place - [09:22:04.916] *** VERIFY DATABASE AFTER BACKUP 09:22:04.916] Collecting verification information...

Re: SnapManager SQL Errors

Oliver pointed me in the right direction - After the email to check the preferred SAN address I noticed the SAN was connected via the Data VLAN and not the iSCSI VLAN. The DBA's had also renamed the server which meant the initiator was keeping the drive mapped but it was possibly affecting mounting the snaps – I disconnected and reconnected with an updated initiator name to match the new server name & reconnected on the correct VLAN and it sorted things out.

Hi, Its a Windows 2003 sp 2 VM server (running on ESX 3.5) using SnapDrive 4.2.1 and SMSQL 2.1.1 and SQL 2005 Three luns f:/g:/h: for database, logs & tmpdb Verification server is the same as the SQL server (ie it does its own dbcc check) The SAN connection is via IP address - what needs to be able to resolve to what ?

Re: Deleting files from snapshots
by Fox, Adam 26 Jun '08

There is no approved or unapproved way to do this. It's not possible. The closest thing you can do is to put a Datafort in front of the controller and encrypt everything. Then you can shred the keys that encrypted the files in question. It doesn't delete them per se but it makes them unreadable. -- Adam Fox ------------------------ Typed with my thumbs on a very small keyboard. ----- Original Message ----- From: Francois Joubert <francois.joubert(a)imagination.com> To: NetApp Toasters List <toasters(a)mathworks.com> Sent: Thu Jun 26 11:00:46 2008 Subject: Deleting files from snapshots Hi Is it possible to delete a limited set of files from all snapshots without having to delete every snapshot in which those files appear?
